Overall, it's pretty good!
A few notes to improve on though:
- Thumbnail composition is imo a little eh, not bad but just could be better
- Title could be more intriguing, e.g. "Is COD MW3 Worth it??". Giving viewers the answer to the question the video answers in the title means many will not look further.
- The scene at 0:11 could be edited better, e.g. each caption could appear separately, maybe with some "pop" sound effect when they show up.
- The subtitling at the very beginning is superb, it's timed correctly, well positioned, and big enough to read but not be obnoxious at the same time. Then, you just stop doing that and the subtitling becomes infrequent, not very well timed, and even looks different. Pick one of the two styles to use, and imo pick the subtitle everything style. I think its clean and (sorry if this is insensitive) with your lisp it'll help open up your audience to people who might struggle to understand you all the time (e.g. foreign speakers, people who are hard of hearing, etc)
- I'd try to script reviews like this, it'll help keep them on topic and prevent doubling back or making mistakes. There aren't many in the video but it did happen a couple times to notice, and in general it felt very all over the place
